MERTZ, Liliane Marcia et al. Physiological and sanitary quality of cawpea seeds processed in gravity table. Rev. bras. sementes [online]. 2007, vol.29, n.3, pp. 1-7. ISSN 0101-3122. http://dx.doi.org/10.1590/S0101-31222007000300001.
The objective of this work was to evaluate the effect of the gravitational table in the sanitary and physiological quality in seeds lots of (Vigna unguiculata (L.) Walp). After the cleanness, seeds of four genotypes (Peanut, Bay, Mosqueado and Preto) had been submitted to the action of the gravity table with discharge divided in three fractions: superior, intermediate and inferior. It is admitted himself as inferior extremity, the situated one in the lowest point of the discharge when considered the lateral inclination of the table and, as superior, the opposing one. Physiological quality of the seeds was evaluated by germination test and vigor (accelerated aging, electric conductivity and cold test). For evaluation of the sanitary quality the blotter test was used. It was observed that the separation of the seeds through the gravitational table provided positive alterations in the physiological and sanitary quality of the lots of beans-small seeds for all the evaluated genotypes, justifying her use in the improvement of seeds of beans-small.
